The Galaxy S4 is officially available for pre-order from AT&T and U.S. Cellular in America, but Samsung USA has listed five versions for its flagship device on its website.

Each of these Galaxy S4 models – for Verizon, AT&T, Sprint, T-Mobile and U.S. Cellular – have their own dedicated page and their all listed as coming soon. However, pricing details aren’t mentioned at this time and you can’t purchase any model directly from Samsung yet. Pre-order links for AT&T and U.S. Cellular are present though, directing you to each mobile operator’s Galaxy S4 order page.

In case you were wondering, all five devices pack a 1.9GHz quad-core Snapdragon processor – no Exynos 5 Octa versions here – and, curiously, internal storage is not mentioned for either model.

For what it’s worth, Samsung only lists the White Frost model for Verizon and Sprint, while Black Mist versions are present for the other three carriers at this time.

However, it’s pretty clear from each page that we’re looking at a different U.S. model. Samsung explicitly lists the carrier on each product page (see gallery below), and the model operator has its logo plastered all over the back of the handset – or at least four of these five carriers do, with Sprint’s unit being the only one not carrier-branded.

Each Galaxy S4 page also reveals the product model number for each carrier, and, unsurprisingly, they all match with the model numbers spotted in recent FCC filings. At the time they were discovered, the filings were believed (and rightly so) to describe U.S. Galaxy S4 versions, although no model was named in the public documentation.

Without further ado, here are the model numbers for five Galaxy S4 models that will be available in the region:

Other regional carriers are also rumored to launch the Galaxy S4 in the U.S., including MetroPCS, which was previously said to also get the SCH-R970 model, and Cricket.

T-Mobile is expected to launch the handset around May 1, for $99.99 without a contract but with monthly installments, while Verizon and Sprint have not mentioned any details about their Galaxy S4 versions.

The Galaxy S4 is also rumored to be available for pre-order from Staples and Walmart, although the retailers have not posted any official announcements yet.
